VAIOBIZER FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Patent.

Patented Feb. 8, 1921.

To all whom it may concern Be it known that I, VVILLIAM MORGAN, a subject of the Kingdom of Great Britain, residing at 38 Wellington road, Birmingham, in the county of Warwick, England, have invented a certain new orlmproved Vaporizer for Internal-Combustion Engines, of which the following is a specification.

This invention comprises a vaporizer for internal-combustion engines, adapted to vaporize fuel which has been delivered from a jet or the equivalent by gaseous pressure difference created by the engine, in which the quantity of liquid fuel thus delivered from the said jet or the equivalent is regulated by the variations in the said gaseous pressure difierence, and in which provision is incorporated for admitting inert gas to be utilized as the carrying medium for the fuel thus delivered.

The inert gas to be thus admitted is advantageously maintained at, or substantially at, atmospheric pressure. To provide for this the ingress provision for the inert gas is conveniently in communication with provision in which-' inert gas is maintained at substantially atmospheric pressure, and said ingress provision is constricted to appropriately confine and regpilate the quantity of inert gas admitted. 0 means of regulating the ingress of the inert gas other than constriction need, therefore, necessarily be em loyed.

onveniently I may, utilize as the inert gas, exhaust gas from the engine, but additionally or alternatively I may use any other suitable inert gas.

I In a convenient embodiment of the resent invention, the fuel, prior to passing t rough the vaporizer, is suitably sprayed 'by Suetion effort upon a jet or the equivalent by the engine, the said jet or equivalent being supplied by a floatchamber or other suitable source of supply. The fuel is then adapted to traverse the vaporizer." The vaporizer is also adapted to be traversed by inert gas or vapor, which, being conveyed in company with the fuel, functions as a carry-' ing medium therefor. The passage of the fuel and its carrier medium through the vaporizer may be effected by the suction effort of the engine, or by other means, such for instance as a pump.

In certain embodiments of the invention,

vaporizer, such exhaust gas bein a minor quantity of air may be admitted with the fuel to the vaporizer.

In order that this invention may be clearly understood and readily carried into practice, reference may be, had to the appended explanatory drawing, which illustrates in sectional elevation, one form of vaporizer according to the present invention. I

In the arrangement illustrated in the drawing, the vaporization chamber a is of elongated form disposed vertically and encircled by a jacket in which exhaust gas is adapted to be circulated, the fuel ingress conduit 0 and. fuel egress conduit 6 being arranged to adjoin respectively the upper and lower parts of the vaporization chamber. d is an ingress aperture for admitting inert gas to the up er part of the vaporization chamber a. aid ingress aperture 01 is appropriately constricted, as for instance by a constricting member or perforated casing e, in which perforations are provided of capacity adapted to restrict the admitted inert gas in an appropriate degree. Externally of the said constricting casing e, a second perforated casing f is incorporated,

adapted to leave an intermediate jacket space. To the interior of said casing f, exhaust gas is admitted from the jacket of the enabled to escape. through the distribute erforations in the casing f, with such free om that within said perforated casing f an atmosphere of inert gas prevails at-substantially atmospheric pressure. 9 is a filter by which the inert, gas entering the vaporizer is cleansed.

The ingress conduit 0 for the fuel may be adapted to receive the latter in company with a minor quantity of air after the said fuel has been extracted from a jet or the equivalent by a gaseous pressure difference created by the engine in the manner,.for inegress conduit 7), in the manner, for instance,' described in my concurrent application No.

148,618 filed February 14, 1917.

What I claim as my invention and desire to secure by Letters Patent is 1. A vaporizer for internal combustion engines in which the inert gas is admitted to function as the essential carrying medium for the fuel prior to the mixture With the main air charge, and throughout the time,

during Which it is being vaporized by heat, including a chamber from Which the inert gaseous medium is adapted to be admitted at substantially atmospheric pressure, the said chamber being adapted to have admitted a part of the exhaust gases, said chamher having means of egress to the atmosphere other than the main egress provision I '20 including a chamber from which the inert assesses gaseous medium is adapted to be admitted at substantially atmospheric pressure, said chamber being adapted to, have admitted thereto part of the exhaust gases, said chamher having means of egress to the atmosphere other than the main egress provision for the exhaust, and by which means of egress the pressure of the exhaust gases admitted to said chamber or space is released, said chamber being provided With enveloping means formed with perforati ns" distributed over its outer walls, whereby communication between the interior of saidchamber and the atmosphere is afforded.

In testimony whereof I affix my signature in presence of two witnesses.
